Air pollution may be a leading global cause of death

New research has found that air pol lution is one of the leading causes of death worldwide, far surpassing smoking, malaria, and other significant factors. Air pollution may increase the risk of death significantly more than other factors, such as smoking. Researchers have found that air pollution is a leading cause of global death. In fact, they claim that it can raise death risk significantly more than other major causes of loss of life, including smoking, malaria, and general violence. The research, which now appears in the journal Cardiovascular Research, suggests that policymakers, health organizations, and the media should be focusing far more on air pollution, given the severity of its effects. Air pollution and human health Over the years, research has definitively demonstrated the negative health effects of air pollution. It is associated with an increase in cardiovascular diseases, such as heart attacks and strokes, as well as chronic conditions such as asthma. It also has adverse effects on pregnancy, such as preterm birth. The study authors note that some air pollution is present in the natural world, such as significant amounts of dust in parts of Africa and in the form of particulate given off by wildfires in various places around the world. A sophisticated new model. To determine the effects of air pollution on global mortality, the researchers developed a sophisticated model that can determine the way in which air pollution interacts with a range of factors. They then applied this model to data detailing death rates in different global locations. They also used a new model to estimate global death rates. 8.8 million predicted deaths The study found that air pollution is one of the major global causes of death. The researchers estimate that during 2015, around 8.8 million people died as a consequence of air pollution. This represents the shortening of global life expectancy by almost 3 years, on average. By way of comparison, in the same year: Smoking tobacco caused around 7.2 million deaths AIDS caused 1 million deaths Diseases carried by parasites or insects caused 600,000 deaths All forms of violence, including wars, caused 530,000 deaths. The greatest effect that air pollution had on health was related to cardiovascular diseases, which accounted for 43% of these global deaths. In terms of age, it was overwhelmingly the case that older people were most at risk. In fact, approximately 75% of the deaths occurred in people over the age of 60.
